RVETING ATTACHMENT FOR POWER-PRESSES.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed July 2l, 1904. SerialvNo. 217:458.

To all whom, it may concern:

Be it known that I, HENRY J. HINDE, a citizen of the United States, anda resident of Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements-in Riveting Attachments forPower- Presses; and I do hereby-declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to a riveting device or attachment foruse inconjunction with any power press or machine having a reciprocatingplunger and a horn or suitable anvil on which to rest the work.

The object of my invention is to provide a riveting-tool of thecharacter indicated that is simple in its construction and operation andadapted to be readily adjusted to operate on rivets having flat, oval,or conically-shaped heads, as the nature or style of the work beingriveted lmay demand.

J- The invention is fully described in the following specifcation andshown in the accompanying drawings, in whichy Figure 1 is a sideelevation of my invention, showing a portion of the machine to which itis attached. Fig. 2 isa front elevation thereof with theoperating-plunger and attached riveting apparatus in lowered position.Figs. 3 and 4 are plan views of Figs. 1 and 2, respectively; and Fig. 5is a view of the anvil and associated riveting parts.

Referring to the drawings, A represents the leader-frame in which theplunger B reciprocates, and C the anvil or work-supporting horn ofV anordinary type of power-press.

The riveting attachment in which lie the features of my inventioncomprises the holder l, the swivel or turret-head 2, which latter hasits upperportion suitably bored to adapt it to loosely lit over and turnupon the lower reduced portion 3 of the holder l, and the riveting-tools4 and 4', which are carried by the turret-head 2. A vertical tongue orboss 5 is formed on the upper surface of the holder l for enabling theholder to be bolted or otherwise rigidly secured to the free end of theplunger B. The turret-head 2 is rotatably secured to the under side ofthe holder l by 5 5 l, means of a bolt 6, which passes through said sideof the holder l diametrically opposite l the concaved pockets 16 andl16' of the anvil,` hereinafter described, and in circularly-aliningposition therewith and are of suitable size to permit theflanged-portions 10 of the tools 4 and 4' to reciprocate therein whenturnedV in vertical alinement therewith. The po tion of the pockets l111 is shown by ,d o

lines in Figs. 3 and 4, one being positionedn vertical alinement withthe rear portion of the oblong projection 7 and the other to theleftthereof. A coiled compression-spring 1.2 is mounted in each pocket l1for'a'ctuating the tools 4 and 4 to return to their normally extended.positions after being forced within said pockets by an aliningobstruction in the work. These pockets are so positioned that when theturret-head 2 is turned in proper position to enable one of said toolsto head a rivet, as hereinafter described, the idle or auxiliary toolwill be in vertical alining position with the diametrically oppositepocket 11, thus enabling it to have a reciprocatory movement thereinshould it strike any portion of the work being riveted on its descendingmovement, while the operating-tool is re- I tained in rigid positionWithin the turret-head `2 by reason of its upper end abutting againstthe under side of the holder 1, as shown in Figs. 1 and 2.

The object of the two riveting-tools 4 and 4 is to provide means in thesame instrument for operating on rivets having two styles of headswithout the necessity of stopping the work and changing the rivetingattachment, the said tools being provided with differentlyshapedrivet-head-receiving sockets or made perfectly fiat for this purpose.

The turret-head 2 is retained in properlyadjusted position by means ofthe springpressed pull-pins 13, Vwhich are reciprocally mounted in thebosses 14, formed on opposite sides of said turret-head and have theirinner sesr AVAiLABLE Coe` ends in engagement with suitable notchesprovided on the periphery of the reduced portion 3 of the holder 1. l

The anvil or Work-supporting horn C is provided on its forward edge witha recessed 'i lor cut-away portion 15, in which is rigidly bolted thehardened block This block is provided at its forward corners with theconcaved pockets 16 arid 16' for receiving and heading the end of arivet as the samev is forced downwardly therein by the operation of theheading-tooland is 'cut away between and at the rear of 'said pockets,as shown-'at 17, to form a recess or seat for the lower pressure-plate1'8. The plate 18 is normally A.held in elevated position, as shown inFig. 1,

.as far'through the workasthe head thereofv Vwill permit, and 'this maybe regulated by `turning the holt 2O in the proper direction.

The object 'of -this pressure-plate is to firmly ld the two sheets beingriveted against 'the ting-tool during the heading oper-ation, therebypreventing the rivet from upsetting 4'and expanding between the sheets.

In the'operation'of my vinvention the work or sheets 21 'are placed 'onthe elevated pressure-plate 18 with the rivets 22 passing through thesame from the upper side to-enable the rivet being Y'headedlto have itslower or small of the rigid tool 4 the idle or auxiliary heading-tool 4'is permitted 'to fmove within the alining receiving-pocket 11 againstthe pres-` sure of the lspring 12, should it strikea rivethead or otherobstruction in the Work. Should the tool 4 be in operation, as showninthe gures of the drawings, and it be desired to operate on a rivet'having a differently-shaped head, as is very often the casein the'sameor diiferent classes of lworlnor to 'head'a rivet inserted through l'thework at the opposite side of the anvil C, the same may be readily andeasily accomplished by releasing the pullpins 13 from engagement withthe'notchesin the lower reduced portion of the holder l and turning 'theturret-head to the left 'until the heading-'tool 4 is in position tooperate idly within the proper pocket 11and the headingtool 4 is in avertical plane with the pocket 1.(3 at the .right-hand corner of ltheanvil C and rigidly abutting against the undei` side of the holder. Itis therefore apparent that by turning lthe swivel-head 2 one of theheading-tools may be thrown either to the right or.

left hand side of the' anvil or horn C, thus making it possible to headrivets close to the walls on shoulders or corners, which may be eitheron the right or left hand side of the work.

It is obvious that while I have shown the turret-headof 'my invention ascarrying but two heading-tools the same may be provided with agreater-number, if desired, so 'as to enablea variety ofdifferently-shaped rivet-'heads to be operated on without stopping thework and changing the riveting attachment, land also that such changesin the form, proportion', and minor details of construction 'of 'theparts as fairly fall within the Asc'ope of my i'nvention vmay be madewithout departing from the spirit or sacrificinga'ny 'offtheadv'antagesthereof. I further wish it understood that while I have described Emyinvention as heading a rivet on the under sidefof the vwork gthe 'samemay b'eiope'rat'ed -with the rivet i'n 'reverse position, so that '-theclenching-'head-of the rivet is formed by contact of the 'end thereofwith the operative tool 4 or t'finstead of the pocketin the anvil. A

Having thus described my invention, -what Iclaim-as new, and desirertosecure by -Letters Patent, is-

1. Inamachineof the class described,'a plunger, an anvil having twospaced concaved fportions for forming the'lower heads of a rivet, amember xed to said plunger and reciprocal therewith, a swivel on saidmember, a series of riveting-tools carried by said swivel and'adapted tobe moved by a movementof said swivel to throw either one into operativeposition over one or the other of said concaved'portions.
